A client with C6 tetraplegia wants to propel a manual wheelchair independently. Which rim modification best supports this goal?
Answer: Vertical projections on the push rim
Vertical projections (quad pegs) allow clients with limited hand function to hook wrists or palms over the rim for propulsion.
Which power wheelchair drive configuration provides the tightest turning radius?
Answer: Mid-wheel drive
Mid-wheel drive places the drive wheels at the center of the chair, allowing it to pivot nearly in place for the tightest turning radius.
A bariatric client weighing 350 lbs needs a manual wheelchair. What is the minimum weight capacity category that should be considered?
Answer: Extra heavy-duty (450 lb limit)
Extra heavy-duty chairs rated for 450 lbs provide an adequate safety margin above the client's 350 lb weight.
Camber on a manual wheelchair's rear wheels primarily improves which performance characteristic?
Answer: Lateral stability and propulsion efficiency
Outward camber lowers the chair's center of gravity and widens the base, improving lateral stability and placing the push rim in a more ergonomic position.
A client reports shoulder pain after six months of manual wheelchair use. Which seating adjustment should be evaluated first?
Answer: Seat-to-floor height (axle position)
Incorrect axle position relative to the shoulder alters propulsion biomechanics and is the leading modifiable factor in wheelchair-related shoulder injury.
Which power wheelchair input device is most appropriate for a user with only reliable head movement?
Answer: Head array
A head array uses proximity sensors or switches around the headrest to detect head movements, providing directional control for users with full head range of motion.
What does 'power seat functions' on a power wheelchair NOT typically include?
Answer: Powered anti-tip deployment
Anti-tip wheels are passive mechanical devices; powered anti-tip deployment is not a standard power seat function category, whereas tilt, recline, and legrests are.
